Build vs. Buy: Hidden Risks of a Homegrown LIMS (and why Lockbox is the Better Choice)

What is a Homegrown LIMS? 

A LIMS developed within the organization where it will be applied is often called a homegrown, in-house, or custom-built LIMS system. When a laboratory outgrows Excel or hasn’t yet found a commercial product to meet their needs, a homegrown LIMS may seem appealing, based on expected cost savings, customization, and quick development to solve immediate workflow challenges. However, as the lab continues to grow and evolve, this custom system becomes a liability – difficult to scale, validate, and support. Over time,  the limitations on the lab’s efficiency, compliance readiness, ability to adapt to new requirements, and dependence on siloed development knowledge become apparent. 

Here we outline the most common risks of building a LIMS internally and provide guidance on when it may be time to transition to a purpose-built LIMS designed to grow with your laboratory: 

• Customization challenges
• Lack of scalability
• Maintenance and support issues
• Lack of reliability
• Compliance risks
• Issues with integrations
• Hidden costs

Customization Challenges of a Homegrown LIMS

There are many pros and cons of having total control over the code and architecture of a LIMS system. Laboratories are often attracted to custom-built LIMS systems because they think they can tailor the system to their specific needs, instead of making their processes fit a pre-built system. In reality, however, software developers are often limited in scientific knowledge and understanding of lab workflows, which leads to solutions that don’t fully meet the users’ needs. Additionally, internal developers may not follow industry best practices for coding, software development, user requirements, design specifications, and data security, increasing long-term risk and technical debt. 

Lack of Scalability

Homegrown systems often face significant challenges when it comes to scaling custom features as the laboratory evolves or throughput increases. Laboratory processes are continually changing, which may be difficult to accommodate with a system that is not designed for easy re-configuration. Increasing throughput typically strains a homemade system that wasn’t originally designed for processing large amounts of data. Faced with these limitations, laboratory staff are forced to quickly find workarounds, which may include storing data outside of the LIMS or not using the LIMS at all. This returns your organization to the untenable situation that motivated your design of a homemade system in the first place.

Maintenance and Support Challenges of In-House LIMS

As laboratories grow, homegrown LIMS systems become increasingly difficult to maintain. In many cases, there is often a lack of consistency in development practices and system documentation. Often, in-house systems are missing an entity relationship diagram that clearly explains how objects interact or connect to each other, which makes handover to another software team difficult. This limited documentation creates a significant risk when the original LIMS developer leaves the organization or retires. And the need to assign a staff member to complete bug fixes may require removing a valuable asset from the laboratory to work on solving software headaches.

Reliability Risks of Homegrown LIMS

Homegrown or custom-built LIMS often suffer from limited reliability, especially when performance issues or bugs persist longer than an acceptable timeframe. Debugging typically falls on internal staff who may lack the time or specialized expertise needed to support the LIMS. Additionally, in-house systems can be expensive to maintain due to the ongoing cost of hardware infrastructure or cloud services.

Why Homegrown LIMS Fall Short on Compliance and Security

Homegrown LIMS systems are often unreliable for laboratories pursuing certifications or working in regulatory environments. These in-house solutions typically lack built-in support for audits, validation, or regulatory standards. Validating the software life cycle using the installation qualification (IQ), operational qualification (OQ), and performance qualification (PQ) method is much more difficult in home-built systems compared to commercially available products. This is because custom systems lack vendor support, extensive documentation, and standardized design.  As a result, there is a high risk of non-compliance due to incomplete logging, insufficient access controls, a lack of differentiation between licensed and non-licensed users, and missing audit trails. Additionally, custom-built LIMS often receive limited security updates or vulnerability patching, leaving critical laboratory data vulnerable. Implementing single sign-on and multi-factor authentication may be more challenging in home-built systems.

Integration and Data Management Challenges in Homegrown LIMS

Homegrown LIMS systems are often incompatible with modern lab tools, instruments, or cloud platforms, lacking the APIs, connectors, or partner ecosystems that support seamless integrations. Developing custom APIs to connect laboratory instruments is time-consuming, expensive, and requires specific expertise that many labs do not have in-house. 

Hidden Costs of Building Your Own LIMS

There are many hidden costs associated with developing a homegrown LIMS system. Laboratories often lack internal staff with the technical expertise needed, leading to outsourced development work or temporary hires, which can be a significant expense. Oftentimes, LIMS projects are larger than originally estimated, leading to the need for a large product development team. In many cases, scientists are pulled away from their core responsibilities to build or maintain the system, spending valuable time on LIMS development instead of doing science. Additionally, if the developer leaves the organization, time and resources must be spent training the next developer to maintain and modify the system.

In-House LIMS Red Flags: When It’s Time to Buy

It is time to consider a new system if you are experiencing any of the following: 

1. Your homegrown system cannot support new workflows, users, or compliance requirements. 
2. Your lab staff has made frequent improvised workarounds, still relies on manual processes, stores data outside the LIMS systems, or adjusts lab processes to fit the LIMS. 
3. You have a large software development backlog that outpaces bandwidth.
4. The leadership of your organization is demanding faster turnarounds and better reporting.
5. The throughput in the lab has outgrown your current system.
